Two of three people accused of attacking CPS worker in NW Houston appear in court

A Child Protective Services worker is recovering after police say she was held against her will and beaten while trying to leave a family's home last night. We're learning new details about the two men and the woman accused in the case and what went on during that unannounced home visit.

In court this morning, Karissa Ferrigno and Shane Douglas stood accused of attacking the CPS case worker as she conducted an investigation into the care of a one-year-old child.

It happened at the Somerset complex Tidwell near Highway 290 in northwest Houston.

The worker was discussing with the family about placing the child with relatives during her investigation into medical neglect and abuse.

The case worker was leaving the apartment, when a third person, Troy Davis, allegedly slammed the door shut, trapping the worker inside. The alleged details read in court are chilling:

"Defendant Davis then punched her with a closed fist on her forehead and pushed her against the wall by her neck and began to choke her. She stated she lost consciousness and when she woke up, Davis was still on top of her," read the court clerk. "At that point, she heard the defendant, Mr. Douglas, ask Mr. Davis if he wanted him to finish her."

But it didn't stop there. Police say Davis threatened the case worker with what she described as a 'dagger' and Ferrigno began to choke her. That's when officers arrived.
